Provided is an automotive dome light such that there is no need to use a mold having a sliding structure, and that a housing can be prevented from dangling. The automotive dome light (100) is such that a light assembly (40) provided with a lens (10), a housing (20), and a bus bar (30) is installed on a reinforcement (60), with a roof panel (50) in between, and that the housing (20) is provided with resin clips (20C) which are anchored to an opening periphery (61) of the reinforcement (60). The resin clips (20C) are each an inverse U-shaped elastic body consisting of a base section (20B) which continues to the housing (20), an inverse U-shaped section (20U) which continues to the base section (20B), a lock (20L) which continues to the inverse U-shaped section (20U) and forms a hook section (20K), and an extension section (20E) which continues to a protruding piece (20T) at the lower end of the lock (20L) and extends further downward. In a state where the resin clips (20C) are anchored to the opening periphery (61) of the reinforcement (60), an opening periphery (51) of the roof panel (50) is in close proximity to the extension sections (20E) of the resin clips (20C).
